RAIL SECURING AND SUPPORTING MEANS.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Application filed June 4, 1914. Serial N 0. 842,998.

To all whom it may concern:

Be it known that I, JOHN W. KENDRICK, a citizen of the United hicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Rail Securing and Supporting Means, of which thefollowing is a specification.

This invention relates to improvementsin rail securing and supportingmeans, and has for its object to provide an improved form of railfastening construction by which the rail may be directly supported upona tieplate or the like, the latter being secured to a tie and supportedthereon in anew and improved manner.

As is well known in railway construction where metal tie-plates areused, as is often the case, the downward thrust of force transmitted bythese plates to the wooden ties results in the partial crushing andwearing of the latter so that they become, in a comparaively short time,unfit for use, and this crushing in the case of creosoted or othertreated ties, often results in the exposure of non-treated portions ofthe tie to the ele ments so as to decrease the life of such tie.

y invention aims to not only provide a new form of fastening devicewhich will eliminate to a great extent the above objections, but I havealso provided an improved form of means for supporting the tie-plateupon and securing the same to the tie so that the said plate may bereadily attached or removed without injury to the tie. These and otherobjects will be set forth and made apparent in the followingspecification and accompanying drawing, in which;

Figure 1 is a perspective view of an improved form of tie-plateindicating in dotted lines the position of a rail supported thereon;

Fig. .2 is a transverse vertical section through a tie showing themethod of attaching a tie-plate to a tie, a portion of the rail beingindicated in dotted lines; Fig. 3 is a perspective view of one of myspikes or dowel pins; and

Fig. 4 is a similar perspective view of one of the hardwood treenails.

Like numerals refer to like elements throughout the drawings, in which10 designates a tie-plate having the base portion 10 from which extendupwardly the spaced apart vertical flanges l0 between which is States,residing at.

adapted to rest the base 10 of a rail indicated in dotted lines inFig. 1. The base portion 10 is suitably apertured at 10, for a purposeto be hereinafter described. Apertures 10 are provided in the Verticalwalls 10", these apertures coacting with lugs 10 formed on the base 10to enable useof a looking or anti-creeping device, not forming a part ofthepresent invention. In attaching the plate to a tie 11, the latter ispreferably partially drilled out or bored at a plurality of locations topermit embedding therein of the treenails 12, formed with a centrallylocated tapered aperture 12. These treenails are chamfered or beveled at12*, at their lower extremity, and are preferably constructed slightlylarger in diameter than the diameter of the holes drilled in the tie 11,so that it is necessary to force them into such holes or bores, therebyinsuring their retention under the stresses and strains ordinarily metwith. These treenails 12 are embedded in the tie 11 so that their topsare substantially flush with the top surface of the tie 11 whereby theywill serve to support or assist in the supporting of the plate 10, theapertures 12 and treenails 12 alining with the apertures l0 in the plateTo secure the plate to the tie, spikes or dowel pins 13, as I term them,are provided, these latter being preferably formed of metal andcomprising a cylin rieal stem 13 and a head 13 semi-spherical in theembodiment shown in Fig. 3. The underside-of this head 13 is cut away toprovide the shoulders or lugs 13, for a purpose to be hereinafterdescribed. The diameter of the stem 13 of dowel pins or spikes 13, ispreferably slightly larger than that of the aperture 12 in the treenails12, and these dowels or spikes 13 are driven through the apertures 10into the apertures 12 in the treenails 12, a close fit being insuredbetween the dowels 13 and treenails 12, so that removal of the formerfrom the latter is resisted.

By locating the rib or shoulder 13 on the underside of head 13',approximately parallel to the vertical walls 10, as shown in Fig. 2 forexample, a claw or pry-bar may have its edge inserted in the spacebetween the underside of' head 13 and top of base 10, as will beapparent, so that initial raising or prying-up of the dowel pin 13 maybe effected when it is desired to remove the plate 10.

structed of Wood, considerably harder and tougher than that of Which thetie is formed,

these treenails 12being ar-.

and furthermore ranged "With the grain substantially perpendic'ulartothe plate 10, greater strength in resisting compressions is obtained. Itwill thus be apparent tie,: as is the case in present-day practice, willbe substantiallyprevented by the supporting of thertie and rail uponthe-topso the treenails 12, this supporti being sufiicient to obtain theadvantages settorth above. Furthermore, I have found-that thefrictionalcontact .betweenthe treenail 12 and the tie 111, and betweenthe formerand the dowel :13, is sufficient to prevent the accidentalremoval of the d0Wel,thereby preventing raising or displacement of thetieplate lO When-in use. Atthe same timeethe device maybe disassembledwith respect to the tie Withcompar-atively little trouble, as

will be apparentto those skillediin the art.

While I; have shown and described the specific embodiment of myinvention, 1 do not Wish to be restricted to such showing anddescription beyond the scopeof the apended claims.

-c W hat I claim is a 1. In combination With a tie, a plurality ofsupporting treenails embedded in said tie, a plate resting upon said tieabove said treenails, the latter and said plate being apertured,. an l'dowel pins-or the likedriven through; said apertures in said plateintothe apertures in said treenails to secure sai plate to said tie,said dowel pins being of greater diameterthan the apertures of saidtreenails.

Copies of this patent may be obtained for that crushing of the fivecents each, by addressing the Washington, D. C.

2.111 combination, a tie-plate, treenails adapted to be embedded in atie, said plate and treenails being apertured, and'fastening membersadapted to be driven through the apertures in said plate into theapertures in said treenails,'said members being provided withhemispherical heads, said heads being provided with a rib or shoulder onthe under side thereof.

3. In combination, a tie-plate for supportinga rail, treenails-adaptedto be embedded in a tie said plate and said treenails being providedwithcylindricalapertures, and cylindrical fastening members adapted to bedrivenv through the apertures in said plate into the apertures in saidtreenails, said fastening members being of larger size than theapertures in said treenails,-said fastening members being provided ,Withheadseach having arib-or shoulder on the under side thereof. a I
